This necessitated making HTMLParser ref-counted, and having it register itself with Document when created. That makes it possible for scripts to add new input at the current parser insertion point. There is now a reference cycle between Document and HTMLParser. This cycle is explicitly broken by calling Document::detach_parser() at the end of HTMLParser::run(). This is a huge progression on ACID3, from 31% to 49%! :^)
